ESP8285 M4 WiFi Module
Basically an ESP8285 module is an ESP8266 Module with additional 1 MB of Flash memory and the ESP8285 can even bear high temperature upto 125℃ (the one for ESP8266 is just 85℃). More important, the code programmed in ESP8266 can also be used for ESP8285.
The core processor of the ESP8285 M4 IoT module uses the cost-effective chip ESP8285. The chip integrates an enhanced version of Tensilica’s L106 Diamond Series 32-bit core processor in a smaller package with on-chip SRAM. The ESP8285 has a full Wi-Fi network capability that can be used independently or as a slave to other host MCUs. When the ESP8285 hosts an application, it can be launched directly from external Flash. The built-in cache helps improve system performance and optimizes the storage system. In addition, the ESP8285 can be used as a Wi-Fi adapter via the SPI/SDIO interface or I2C/UART port for any microcontroller-based design.
The ESP8285 M4 wifi module supports the standard IEEE 802.11 b/g/n/e/i protocol and the full TCP/IP protocol stack. Users can use this module to add networking capabilities to existing devices or to build separate network controllers. The ESP-M4 module provides Zui’s great utility at low cost, providing unlimited possibilities for Wi-Fi functionality to be embedded in other systems.
Description
ESP-M4 is encapsulated by the excessive efficiency chip ESP8285, which is sufficient to ESP8266 chip plus 1M Flash. The chip ESP825 is encapsulated a sophisticated Tensilica’s L106 32-bit CPU, alongside SRAM. ESP825 has the entire and full WiFi perform, which can used independently and alsoused as a slaver with different Hoster MCU, which can begin instantly from the out-built Flash. As well as, the built-in high-speed buffer is profit for the system efficiency. Particularly, ESP8285 are sometimes used as a WiFi adapter by SPI/SDIO and/or I2C/UART interface, when it is utilized to the alternative MCU design.
